Stone tools found in the Russian
Altai confirm a human presence in central Asia at ca. 800,000BP. Who were these
hominins and what is the evidence? Perhaps
it was Homo antecessor (pictured below from Wikimedia commons (2018))?
Karama is an open-air site in
southern Siberia. It lies approximately 400km SSE of the city of Novosibirsk on
the banks of the Anui River in the northwest of the Altai.
Sites in the region were first
noted when 1959 with the discovery of a few flint flakes, followed by petrified
bones of large animals in the Iskra Cave in the vicinity of the settlement of the
same name.
It took another twenty years, for
a systematic, series of excavations to begin under the direction of the
Siberian archaeologist A. P. Okladnikov. In total, more than 30 caves and some
open-air, sites have now shown evidence
of Palaeolithic occupation in the Anui Valley. This unique series of sites
includes, Denisova Cave, Okladnikov Cave, Strashnaya Cave, Chagyrskaya Cave, Razboinichya
Cave and Karama. The Karama site was discovered in 2001. Presumably this was
excavation no.1, on which I have been unable to find any information. The
details below refer to excavation no. 2.

the site from across the valley, Shunkov (2018) and below initial stages of the

On the likely hominins occupying the
site and lithics discovered, Zwyns (2014) helpfully translates and summarises papers
originally, in Russian: “According to Derevianko, the Altai was first colonized
by small populations of Homo erectus/ergaster starting from c. 800 ka, that
subsequently disappeared from the region c. 500 ka.
The site that would best
represent this first wave of human occupation is Karama, along the Anuy River.
The diversity of the exotic flora is said to fit with a Middle Pleistocene
attribution and the RTL dates of 643 +/- 130 ka and 542 +/- 110 ka have
been obtained on the lower portion of the sequence
(layers 8–14). Although the identifiable artifacts do not include handaxes,
Derevianko and Shunkov tend to emphasize elements that would fit with an
Acheulean attribution. The technology is described as cores on pebble blanks and
flakes with subparallel dorsal pattern. The tool-kit includes various kinds of
scrapers (including naturally backed examples), Clactonian notches, and
choppers. More surprising is the reported presence of core-like endscrapers with
abrupt retouch. Derevianko acknowledged that the first Lower Paleolithic
occupation of the Altai is elusive and likely represents a short-term event.”

On the possible assignment of the
early Acheulian tools found to a Clactonian facies it is interesting to look at
Stringer (2006), italics mine: “..there are further clues to the nature of the
Clactonian from a site.. at Ebbsfleet. Large-scale excavations there for the
Channal Tunnel Rail Link and associated engineering works since 1997 have been accompanied
by archaeological investigations and, in 2003.. the skeleton of a straight-tusked
elephant was found surrounded by about 100 stone tools – Clactonian tools. As
at Swanscombe, pollen and other evidence suggested that this Clactonian
occupation was early in the warm part of the same interglacial period (about 400,000BP). But the the
association of Clactonian tools and a large mammal skeleton was very
significant because it had previously been suggested that handaxes were the
preferred tools for butchery at this time, yet there are none at Ebbsfleet..”
Therefore there is some precedent
for lithic assemblages lacking handaxes, however the dates for the Ebbsfleet
lithics are far later than those from Karama. On the other hand, the assumed habitats,
climate and, faunal composition of the areas may be broadly similar. Thus an occupation
resulting from an early species migration out of Africa, such as that postulated
for Homo ergaster/antecessor is not out of the question. It also fits with
Stringer’s idea that the hominins that made the Happisburgh footprints 850,000
years ago were Homo antecessor.
However, it was a close analysis
of the palynology of the sediments that confirmed the extremely advanced age of
the Karama site. Bolikhovskaya and Shunkov (2014) summarised the evidence thus:
“The composition of the
autochthonous palynoflora from Karama’s three units comprises over 130 taxa of
various tiers. Pollen of 45 genera and species of trees and shrubs as well as
56 species, genera, and families of herbaceous plants and subshrubs have been
identified. Thirty taxa represent the spore-bearing plant group (mosses, ferns,
lycopods, horsetail, and others).The palynoflora of the lower (strata 13–9) and
medial (strata 8 and 7) Karama units is substantially richer than that of the
earlier examined synchronous sediments at Cherny Anui and Nizhny Karakol that
contained only 25 genera and species of arboreal and shrub taxa. However,
according to the taxonomic composition of the dendroflora and the structure of
paleophytocenoses, the periods of accumulation of these sediments were
relatively close to the interglacial periods reconstructed for Karama. The pollen
spectra from Karama strata 7, 8 and 10–13 contain a considerable number of
elements that are non-typical of modern boreal flora (Picea sect. Omorica,
Pinus sect. Strobus, Pinus cf. koraiensis, Betula sect. Costatae) and nemoral
European, Far Eastern and other taxa (Juglans mandshurica, Carpinus betulus, C.
cordata, C. orientalis, Ostrya sp., Quercus robur, Tilia cordata, T. amurensis,
T. mandshurica, Ulmus pumila, Corylus avellana, Alnus glutinosa, A. incana,
Morus sp.). Many were first recorded in the pollen spectra of the Middle
Pleistocene deposits of the Anui valley. The presence of Pinus sect. Strobus,
Carpinus cordata, C. orientalis, Ostrya sp., Quercus robur, Tilia cordata, T.
amurensis, T. mandshurica, Alnus glutinosa, A. incana, Corylus avellana,
Juglans mandshurica Carpinus betulus, Ulmus pumila, Morus sp., etc. in strata 7, 8 and 10–13 as well as
eco-coenotic features of the exotic taxa found, results of the analysis of the
geographical groups of dendroflora, and other data suggest the Middle Pleistocene
age of the sediments. For instance, hop hornbeam Ostrya sp. and mulberry Morus
sp., belonging to the group of American-Mediterranean-Asian genera, indicate
the Middle Pleistocene age of sediments in the southern Cis-Baikal and Upper
Amur regions (Makhova, 1978; Grichuk, 1982). The interglacial palynofloras of
Karama differ considerably from the Early Pleistocene floras of the eastern
Altai, southern part of Western Siberia, and other mountainous and plain
regions of Siberia and the Far East. They lack pollen grains of subtropical,
broad-leaved species such as Pterocarya, Carya, Zelkova, Celtis, Ilex, Tsuga ,
and other exotic taxa of the pine family that are characteristic of the warm-loving
Early Pleistocene floras of the named regions. This contradicts the idea that
Karama dates back to the Early Pleistocene. However, some researchers argue
that the Early Pleistocene age of the Karama lower unit cannot be ruled out
(Zykin et al., 2005). This assumption is based on paleomagnetic testing of the
entire section that yielded evidence of normal polarity as well as on the
presence of two vertisols in the lower portion of the section. Previously, such
soils were recorded only in Pliocene sediments of Western and Middle Siberia.
This allowed V.S. Zykin and his colleagues to correlate the lower Karama strata
with the Barnaul Lower Pleistocene layers, and, correspondingly, with the
Olduvai subchron. However, we can hardly agree with this assumption, since the
Middle Pleistocene interglacals reconstructed on the basis of the Karama pollen
data differ considerably from the period of formation of the Barnaul strata in
southern Western Siberia in floral, phytocenosis, and paleoclimatic characteristics.
The sediments bearing the Barnaul floral remains were formed in forest-steppe
and steppe zones and in a climate similar to the modern climate, while the
Karama interglacial floras existed under warmer and less continental climatic
conditions than today. The spore and pollen spectra of Karama indicate
considerable faunal changes mirroring numerous fluctuations of plant biomes
caused by climatic fluctuations over four reconstructed stages of the Brunhes
event. The first interglacial recorded in the section corresponds to the
accumulation period of strata 13–10 that can be correlated with MIS 19, or the
Gremyachie interglacial of the Russian Plain dated to 790–760 ka BP. This
period was characterized by a climate warmer than it is now and a dominance of
forest-steppe and forest landscapes.”
Other commentators, also concur
with this dating: from Kuzmin and Kazansky (2019): “Factual information and its
interpretation regarding the geological age of the Lower Palaeolithic site of
Karama (Altai Mountains, Siberia) are considered. It is demonstrated that
palynological data do not allow to date this site to earlier than ca. 800 kya;
archaeological data are consistent with this estimate. The viewpoint of V. S.
Zykin with coauthors, according to which the age of Karama is ca. 1.95-1.77
mya, finds no support in the light of the available geological and paleomagnetic
evidence. The so-called “Karama suite” of the Upper Pliocene of Altai Mountains
in reality does not exist. For the time being there are no reliable data
indicating than the initial peopling of Siberia took place prior to ca. 1 mya.”

ReplyDeleteYour coverage of Siberian archaeology is absolutely interesting to me…in particular, your posts about these amazingly ancient sites, such as Ulalinka and Karama …from which I knew, it´s right to say, only from your blog .
Karama appears to have a more consistent and valid dating…and therefore, seems to be the site that can more effectively contribute to a better understanding on when and how this region was first populated.
Respect to your open question about who where these hominins... I am also inclined to think that whoever had occupied the Altai region 800 Ka ago, must have been a somewhat more brained Homo than, for example… the early H. erectus (or even H. ergaster´s…??) who made the first recognizable (though rudimentary), true Mode 2 handaxes, found at the lowermost layer of Bed 2 in Olduvai Gorge site, Africa, 1,7/1,6 Ma ago.
If this speculation can be valid, I totally agree with you that we can´t rule up H. antecessor as a feasible candidate…as well as a more brained H erectus, I would add.
Not precisely an expert in primitive technology, but in my opinion, this lithics assemblage (composed of relatively simple lithics, judging from the images) appears to be knapped in order to achieve only the very basic functionality expected from each tool. The absence of handaxes should not be surprising…as them, as well as other cutting tool bifacially flaked, are not an always reliable signature of a Lower Paleolithic site. Their presence in many African sites of similar dating (often with some beautifully manufactured tools) could have been due to other reasons than brain capacity, availability of proper raw material and also type of fauna to be hunted…such as complex hierarchical relationships within the human group, possibility of a regular interchange with neighbors, and others related… aspects which could have upgraded the “quality” of the tools…and ultimately, are mainly related with a major or minor demography of a certain region, at a certain time.
At this respect, Derevianko´s appreciations ( included in your post) about an “elusive” occupation of the Altai region at those early times, are giving us an idea on how low their population density could have been…and perhaps also on the degree of isolation in which these Homo developed their existence.
